Allysine–Allysine–Allysine–LysineCattleCrosslinks between four AAs
On:

Desmosine is an amino acid found uniquely in elastin, a protein found in connective tissue such as skin, lungs, and elastic arteries. Desmosine is a component of elastin and cross links with its isomer, isodesmosine, giving elasticity to the tissue. Detection of desmosine in urine, plasma or sputum samples can be a marker for elastin breakdown due to high elastaseContinue Reading

Protein Secondary Structure
On:

Protein secondary structure is the three dimensional form of local segments of proteins. The two most common secondary structural elements are alpha helices and beta sheets, though beta turns and omega loops occur as well. Secondary structure elements typically spontaneously form as an intermediate before the protein folds into its three dimensional tertiary structure. Secondary structure is formally defined by the pattern of hydrogen bonds between the amino hydrogen and carboxyl oxygen atoms inContinue Reading

Heart
On:

Brain natriuretic peptide 32 (BNP), also known as B-type natriuretic peptide, is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume. BNP is one of two natriuretic peptides  “UniProt”. www.uniprot.org. Retrieved 11 August 2022. The 32-amino acid polypeptide BNP is secreted attached to a 76–amino acid N-terminal fragment in the prohormone called NT-proBNP (BNPT), which is biologicallyContinue Reading

On:

Not to be confused with Somatocrinin or Somatomedin. Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin inhibits insulin and glucagon secretion.  “somatostatin”. Encyclopædia Britannica. Encyclopædia Britannica Online. Encyclopædia Britannica Inc.,Continue Reading

Hormones

I am posting all the hormones (or a large number of them) for further reference. This is a serious pain the ass but I think it will be worth it. As ever I am starting with the Wikipedia pages and references. The tags will be crazy until I’m finished andContinue Reading

Thyroid
On:

Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. Bowen, R. (2010-07-24). “Physiologic Effects of Thyroid Hormones”. Colorado State University. Retrieved 2013-09-29. Production of T3 and its prohormone thyroxine (T4) is activated by thyroid-stimulating hormone (TSH), which is released from the anterior pituitary gland. This pathway isContinue Reading
