What is the molecular weight of lysozyme?
approximately 14 kDa
The molecular weight of lysozyme is approximately 14 kDa to 15 kDa and the isoelectric point is about pH 11 [33].
What is ovomucoid in?
Ovomucoid is a protein found in egg whites. It is a trypsin inhibitor with three protein domains of the Kazal domain family. The homologs from chickens (Gallus gallus) and especially turkeys (Meleagris gallopavo) are best characterized.
Is Ovomucin a glycoprotein?
Ovomucin is a highly glycosylated glycoprotein, which consists of a carbohydrate poor subunit (α-ovomucin) with 11–15% carbohydrate and a carbohydrate-rich subunit (β-ovomucin) with 50–57% carbohydrate (Itoh et al., 1987, Kato and Sato, 1971, Robinson and Monsey, 1971).
What foods have ovomucoid?
Egg white contains the more important allergens: ovomucoid (Gal d 1), ovalbumin (Gal d 2), ovotransferrin/conalbumin (Gal d 3), and lysozyme (Gal d 4) [69]. Ovomucoid, which comprises 10–15% of the protein in egg white, is very thermostable and digestion stable, whereas the others are more labile.
How do you find the molecular weight of lysozyme?
Based on the amino acid sequence, the molecular weight of lysozyme is 14300 daltons, which is equivalent to 14300 g/mol.
What is the molecular weight of ovalbumin?
45 kDa
Ovalbumin has a molecular mass of 45 kDa and is composed of 385 amino acids.
Is ovomucoid in egg yolk?
There are three major proteins of concern in egg white: ovalbumin, the major allergen present in the highest proportion; ovomucoid, another egg white protein responsible for the majority of allergic reactions; and ovotransferrin. Egg yolk is an allergen but is not responsible for many reactions.
What is ovomucoid allergy?
The two main allergens are known as ovomucoid and ovalbumin. They are found in the egg white. Ovomucoid is acid resistant and heat stable. People who have an allergic reaction to ovomucoid usually cannot tolerate raw or cooked eggs.
Is Ovomucoid a glycoprotein?
Ovomucoid (Gal d1) is one of the major allergen in hen’s egg. It is a glycoprotein comprising 186 amino acids, and it has a molecular weight of 28000 Da and an isoelectric point of 4.1.
What is the molecular weight of Ovotransferrin?
77.9 kDa
Otrf is a monomeric glycoprotein containing 686 amino acids, with a molecular weight of 77.9 kDa and an isoelectric point of 6.0 [9,10]. The avian transferrin gene is transcripted in the liver and the oviduct.
