China H&Z® L-Pyroglutamic Acid (also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate for its basic form) is a ubiquitous but little studied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam.It is a metabolite in the glutathione cycle that is converted to glutamate by 5-oxoprolinase. Pyroglutamate is found in many proteins including bacteriorhodopsin. N-terminal glutamic acid and glutamine residues can spontaneously cyclize to become pyroglutamate, or enzymatically converted by glutaminyl cyclases. This is one of several forms of blocked N-termini which present a problem for N-terminal sequencing using Edman chemistry, which requires a free primary amino group not present in pyroglutamic acid. The enzyme pyroglutamate aminopeptidase can restore a free N-terminus by cleaving off the pyroglutamate residue.

Arabinogalactan which is made by H&Z® factory is a neutral polysaccharide composed of arabinose and galactose. This sugar is abundant in the xylem of conifers,especially larch (Larix), up to 25%.Soluble in water, insoluble in ethanol.Heating reduces the viscosity.

Mancozeb from H&Z® factory can control of many fungal diseases in a wide range of field crops, fruit, nuts, vegetables, ornamentals, etc. More frequent uses include control of early and late blights (Phytophthora infestans and Alternaria solani) of potatoes and tomatoes; downy mildew (Plasmopara viticola) and black rot (Guignardia bidwellii) of vines; downy mildew (Pseudoperonospora cubensis) of cucurbits; scab (Venturia inaequalis) of apple; sigatoka (Mycosphaerella spp.) of banana and melanose ( Diaporthe citri) of citrus. Typical application rates are 1500-2000 g/ha. Used for foliar application or as a seed treatment.

China H&Z® Crystalline fructose is a processed sweetener derived from corn that is almost entirely fructose. D-Fructose can also be made from sucrose (table sugar) by splitting the fructose and glucose molecules. Crystalline fructose consists of at least 98% pure fructose, any remainder being water and trace minerals. Fructo-oligosaccharide(FOS),is also known as Fucto-oligo, fructose directly enters into large intestine without being digested and absorbed by human body, and in intestine it rapidly promotes reproduction of bididobactirium and other probiotics, so fructose is also called “Bifidus Factor”
