Ovotransferin is a glycoprotein containing a high number of amino acids. Glycoproteins are found in cell membranes and function in cell to cell recognition. They have an important role in protection, structural integrity and cell adhesion.
They also play a part in the elastic fibres of elastin and connective tissue
‘The elastic fiber is formed from the elastic microfibril (consisting of numerous proteins such as microfibrillar-associated glycoproteins, fibrillin, fibullin, and the elastin receptor) and amorphous elastin.’
A reaction with lysyl oxidase transforms soluble elastin into a durable complex cross-linked by desmosine and isodesmosine. Lysine is the amino acid responsible for these cross links.
Desmosine and Isodesmosine are two amino acids found in elastin
They are lysine-derived compounds resulting after total peptide bond cleavage of elastin.
Elastic fibres are bundles of proteins (elastin) found in extracellular matrix of connective tissue and are produced by fibroblasts and smooth muscle cells in arteries. These fibres can stretch up to 1.5 times their length and snap back, the elastic tissue is considered the ‘’connective tissue proper’
Chondroitin sulfate is a proteo glycan, a protein with glycosaminoglycans (GAGs), a family of carbohydrates with the primary role to maintain and support collagen, elastin and plumpness in the cellular spaces. It helps collagen and elastin fibres to retain moisture
As is hyaluronic acid.
L-cysteine is a basic building block of the antioxidant glutathione, the human body's most important antioxidant. Glutathione recharges vitamins C and E as they are used as antioxidants.
It is believed to help in the protection of DNA from chemical damage and detoxification of heavy metals, and it helps keep arteries and airways open. It also activates many important functions of the immune system.
L-cysteine helps the skin defend itself against sun damage. Together with selenium, vitamin C, and vitamin E, L-cysteine helps skin cells form the enzymes that keep a gene called p53 active. This "watchdog" gene triggers a series of steps that cause a potentially cancerous cell to undergo a process called apoptosis, or "cell suicide." When p53 detects changes in skin DNA that could cause cancer, it shuts down the cell. L-cysteine is also important for the formation of the caspases that dissolve the cell once it dies.
