hydroxyproline deficiency

Vitamin A Deficiency Earliest manifestations of vitamin A deficiency is impaired vision particularly in reduced light (night blindness) Persistent deficiency gives rise to a series of changes involving epithelial metaplasia and keratinization 8 The most devastating changes occur in the eyes and are referred to as xerophthalmia (dry eye) First xerosis conjunctivae Buildup of keratin Several parameters were then evaluated related to lung connective tissue metabolism including: (1) total lung hydroxyproline (2) total lung elastin (3) apparent rates for lung collagen synthesis and elastin accumulation and (4) lung and body weights In general the response to protein deficiency and food restriction was more pronounced than to ozone exposure Protein deficiency and food

Estrogens deficiency therefore results in a longer life span of osteoclasts Urinary hydroxyproline level was significantly increased in our patient Hydroxyproline is the major breakdown product of collagen the primary protein of the bone matrix It is considered as clinical index of bone resorption and a major determinant of bone status During bone loss collagen fibrils are broken down

Prolidase (X-Pro dipeptidase EC 3 4 13 9) splits iminodipeptides containing C-terminal proline or hydroxyproline (X-Pro or X-Hyp) to X+Pro or X+Hyp Prolidase deficiency is a rare autosomal recessive disease characterized by chronic ulcerative dermatitis and mental retardation These patients excrete large amounts of iminodipeptides containing

Amino Acid composition and Sequence • Collagen has a unique primary structure represented as - Gly- X-Y • Glycine is one - third of total amino acid content of collagen followed by hydroxyproline and proline account for another one-third of amino acid content of collagen • X- is frequently proline 3-hydroxyproline glutamate histidine leucine or phenylalanine • Y- 4

Deficiency of matrix metalloproteinase-13 increases inflammation after acute lung injury Anita I Sen Takayuki Shiomi Yasunori Okada Jeanine M D'Armiento Department of Pathology Research output: Contribution to journal › Article 17 Citations (Scopus) Abstract Human and animal studies of acute lung injury (ALI) have shown that matrix metalloproteinases (MMPs) play an important role

Synonym: L-Hydroxyprolin Abkrzung: Hyp Englisch: hydroxyproline 1 Definition Hydroxyprolin ist eine nicht-essentielle Aminosure 2 Synthese Im Krper entsteht Hydroxyprolin enzymatisch aus Prolin unter dem Einfluss der Prolinhydroxylase mit Ascorbinsure als Coenzym Die oxydative Umwandlung erfolgt erst wenn Prolin an ein Peptid gebunden ist 3 Vorkommen

Structure Of Collagen Tissue Molecule

Hydroxyproline which is critical for collagen stability is created by modifying normal proline amino acids after the collagen chain is built The reaction requires vitamin C to assist in the addition of oxygen Unfortunately we cannot make vitamin C within our bodies and if we don't get enough in our diet the results can be disastrous Vitamin C deficiency slows the production of

Proline is hydroxylated to hydroxyproline (after the protein is made) by an enzyme that uses vitamin C as a cofactor Vitamin C deficiency does not permit this reaction taking place this loss in OH-pro and its hydrogen bonds makes collagen fragile taking place this

Ascorbic acid is required in several important hydroxylations including the conversion of proline to hydroxyproline (and thus collagen formation e g for intercellular substances and during wound healing) the formation of the neurotransmitters 5-hydroxytryptamine from tryptophan and noradrenaline from dopamine and the biosynthesis of carnitine from lysine and methionine Ascorbic acid

Root development under Pi deficiency: Cederholm Benfey Two peptides named hydroxyproline‐rich systemin I and II (HypSys I and II) were first found to associate with wounding and enhance herbivore resistance in tobacco (Pearce et al 2001 Ren Lu 2006) These two endogenous HypSys are 18‐amino‐acid peptides with three to five hydroxylated prolines attached with six or nine

Hydroxyproline is a nonessential amino acid derivative formed during post-translational protein modification through hydroxylation of the amino acid proline by the enzyme prolyl hydroxylase which requires vitamin C as a co-factor Hydroxyproline is a major component of the protein collagen and plays a key role in the stability of the collagen triple helix

Amino Acid composition and Sequence • Collagen has a unique primary structure represented as - Gly- X-Y • Glycine is one - third of total amino acid content of collagen followed by hydroxyproline and proline account for another one-third of amino acid content of collagen • X- is frequently proline 3-hydroxyproline glutamate histidine leucine or phenylalanine • Y- 4

hydroxyproline (Hyp) on their C-termini Prolidase from Homo sapiens (HsProl) is a homodimeric cytosolic enzyme consisting of two 493 amino acid long polypep-tide chains [9] Each subunit can be divided into two domains: the N-terminal domain (residues 1–184) and the C-terminal domain (residues 185–493) The C-term-inal domain shares the pita-bread fold with other pepti-dases such as

hydroxyproline-564 by immunoblotting in HUVEC (fig S2) With prolonged exposure and sensitive chemiluminescence reagents we detected HIF-1 –OH bands in normoxic cells treated with or with-out GYY In hypoxic cells HIF-1 –OH was undetectable however a faint but detectable band was observed with GYY treatment (fig S2) Together these results suggest that H 2S supplementation can

Tobacco hydroxyproline-rich systemins Hydroxyproline Formation Vitamin deficiency symptoms correlate with their enzyme cofactor function Scurvy a vitamin C deficiency is characterized by bleeding gums loose teeth and poor wound healing all due to weak connective tissue The collagen in these tissues is deficient in hydroxyproline since vitamin C ascorbic acid is required to

id: GO:0019471 name: 4-hydroxyproline metabolic process namespace: biological_process def: The chemical reactions and pathways involving 4-hydroxyproline C5H9NO3 a derivative of the amino acid proline The presence of hydroxyproline is essential to produce stable triple helical tropocollagen hence the problems caused by ascorbate deficiency in scurvy

Hydroxyproline: N/A: N/A: N/A *1 6g is the Adequate Intake (AI) for Omega 3s Adequate Intake is assumed to ensure nutritional adequacy and is established when evidence is insufficient to develop an RDA Next How wide is the range between too much (toxicity) or too little (deficiency) for any nutrient? In the Bathtub curve graph below we see that the RDI is set to cover 98% of all people

Magnesium Deficiency and Decreased Bone Magnesium Since osteoporosis is associated with disorders in which Mg loss occurs estrogen deficiency may cause loss of tissue Mg Postmenopausal osteoporosis is the most common form of this bone-wasting disease Estrogen also interacts with other hormones that influence mineral utilization (infra vide) - both directly and possibly through its effects
